Features And Advantages of 1HP Air cooled Small Hydraulic Oil Coolant Chiller

»The oil viscosity remains constant and featured by a micro temperature controller. The micro temperature controller detects changes in oil temperature from the set value and regulates it with liquid refrigerant.

»220V 50HZ 1PH or 208-220V 60HZ 1Phase power supply for option

» All oil chiller units manufactured by Tongwei have Stainless steel brazed plate type heat exchanger and Oil Tank as the evaporator

»High-quality hermetic Panasonic Brand scroll compressor

»Compact design with portable wheels

»Easy installation&operation,low-maintenance cost

How Does Oil Chiller Works?

The principle of vaporization and heat absorption of Freon in the evaporator is used for cooling.

When the oil chiller is working, the oil pump pumps oil from the oil tank in the machine to the evaporator of the oil chiller for heat exchange, and the cold oil is cooled from the cold oil.

The oil chiller takes the output and sends it back to the storage tank to mix with the hot oil.

The continuous circulation of oil reduces the temperature of the entire oil tank.

The temperature controller of the oil chiller automatically controls the opening and closing of the unit through the temperature sensor, so that the oil temperature is automatically constant at the set temperature.

What Are Types Of Oil Chillers ?

There are two types of precision oil chiller : one is Box Type Oil Chiller ,the other is Immersion oil chiller.

Box type oil chiller is built with oil pump and oil tank;

Immersion oil chiller is no built with oil pump and oil tank , it use Stainless steel coil as heat exchange.

What Are The Main Components of Oil Chiller ?

5.1 Compressor

The compressor is the key mover in Oil Chiller because it produces pressure variations to stir the refrigerant around.

For 3KW chiller , which is with one unit Panasonic brand compressor, using R410A/R407C refrigerant,this brand compress is with high refrigeration efficiency,low noise ,energy saving,environmental protection and durability,safety and stability.

5.2 Evaporator

The evaporator is a crucial component of Oil chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. There are three types of evaporators :304SS stainless steel plate type + Oil Tank as heat exchanger.

SS Plate + Oil Tank Evaporator

5.3 Oil Pump

The oil pump is designed to increase the pressure and the flow of the chilled oil in a closed space.

5.4 Condenser

The condenser for oil chiller is equipped with efficient cross-seam fins and female threaded copper tubes for high heat exchange efficiency and good stability.Its function is to cool down the refrigerant steam released from the compressor into a liquid or gas-liquid mixture.

5.5 Controller Panel

Tongwei chillers use precision digital temperature controller, it RS485 communication port,which can do remote monitoring and control. Simple operation, low failure rate, high safety factor, easy installation.

Spare Part for Oil Chiller

Oil Chiller are used to cool the following oils:

Coolant oil:

Coolant oil chiller is used to maintain the temperature of the coolant, thereby maintaining the surface finish and accuracy of the parts to be machined.

Hydraulic oil:

The hydraulic oil chillers maintain the temperature of the hydraulic oil, thus maintaining its viscosity, allowing the machine tool to work smoothly.

Spindle oil:

The spindle oil chiller is used to maintain the temperature of the spindle oil and prevent the spindle from deforming, thereby improving the surface finish and accuracy of the parts.

Cutting oil:

Cutting oil chiller is used to maintain the temperature of cutting oil, thereby increasing tool life and providing better surface finish and component accuracy.

What are the Industrial Applications of 1HP Air cooled Small Hydraulic Oil Coolant Chiller?

You can use the oil chillers in different industrial chilling applications to control the cooling temperatures you want.

Here are some of the industrial applications where you will use the oil chillers.

▪ CNC Machining Centers

▪ Inner and Outer Grinding Machine Applications

▪ Electric Discharge Machine Applications

▪ Hydraulic Oil Stations and Hydraulic Machinery Applications

Shipping Way of Oil Chiller

As a professional oil chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :

1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.

2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.

3.If you have your own shipment container in your other supplier in China, we can help you delivery the chiller machine to your supplier in any city of China .
